Hace 2 días · We therefore determined the effect of different dose combinations of FOS and L-theanine (termed MT-01/GBL-Memory 1) ... Our tests showed that when L-theanine and FOS are administered in combination, the LD 50 (lethal concentration 50) of MT-01 is higher than 10 g/kg.bw in an acute oral toxicity test (Table S3), ...
